摘要
本文利用由Seasat 卫星测高资料和地球重力模型 GEM-T1 确定的海面地形模型WSST·90B,确定了全球海域的海流,并分别与Levitus 动力海面地形模型和 Engelis动力海面地形模型结果进行了比较。结果表明,WSST·90B和Levitus 模型确定的海流图非常接近,且能较好的反映全球主要海流的位置、方向和流速。
This paper deals with the determination of ocean surface circulation by the modelof sea surface topography WSST·90B, which was deduced by combinating of seasetAltimetric data and geopotential model GEM-T1. The ocean surface circulation is com-pared with those determined by Levitus's and Eegelis's dynamic sea surface topographricmodels respectively. The result shows that WSST·90B can effectively determine globalmain ocean surface circulations.
